Vedclass · Answer

(C) $BOD$ stands for Biochemical Oxygen Demand. It represents the amount of dissolved oxygen that would be consumed if all the organic matter in one liter of water were oxidized by bacteria.High $BOD$ indicates that there is a large amount of organic matter present in the water,which requires a significant amount of oxygen for decomposition by microorganisms.As microorganisms consume this oxygen,the level of $DO$ (Dissolved Oxygen) in the water decreases significantly.Therefore,a high $BOD$ is a direct indicator of high water pollution and low $DO$ levels.
